828a15cfdb svg_loader: class attribute added 
It's the first step in introducing the css inline style sheets into tvg.
For now the class attribute is set only for SvgNodes (not for grads),
it's not used yet.

04d3bb0ec0 svg_loader: fixing cyclic cloning of nodes 
The reference node doesn't have to be placed inside the defs block,
so when refering to it, it is necessary to search the entire node tree.
In case of invalid svg file this can lead to circular references.
Added prevention against such a sutuation.

properly read by the svg loader.

4485db4f15 svg_loader: a function to establish shapes boundries without a stroke introduced 
To handle the objectBoundingBox units, the shape's boundaries have to be known.
According to the SVG standard, a stroke shouldn't be taken into account. Since
the bounds() api uses the shape's stroke information, a new function is introduced,
that compensates this and returns boundaries without any strokes.
